Abstract
A method for detecting the opening of the openable sections of a motor vehicle by a detection device. The device includes at least two ultra-high-frequency communication modules, each located on a different openable section and connected to an electronic computer. An opening angle of a first openable section is determined based on: a first distance between a rotation point of the first openable section on which a first communication module is located and a position of a second module when the two openable sections associated with the two modules are closed; a second distance between a rotation point of the first openable section and a position of the first module on the openable section; a distance between the two modules when the two openable sections associated with the two modules are closed; a distance between the modules, determined by a time of flight of ultra-high-frequency radiation exchanged between the modules.
